Sunspots and aurorae

Last night there was yet another (faint) auroral display visible from Norfolk - if you happened to be where there was a clear sky! Perhaps not surprisingly, the Sun's face is covered with sunspots today: there is a link between these regions of magnetic disturbance and coronal mass ejections...

If it's clear tonight or tomorrow there may well be more auroral displays, as well as the crescent Moon sneaking up on Venus at twilight.

As always: never look at the Sun directly or with optical aids: I use special filters!
